MACHINE FOR ROUNDING STRAPS.

SPECIFICATION forming ,part of Letters Patent No. 291,790, dated January 8, 1884.

Application filed January 16, 1883. (Model.)

To all whom t may concern.-

Be it known that I, A. O. SIMS, a citizen of the United States, residing at Burlington, in the county of Coffee and State of Kansas, have invented certain new and useful Improvements in Machines for Rounding Straps 5 and I do hereby declare the following to be full, clear, and e'Xact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in machines for the manufacture of harness, and has for its object to produce a smooth and uniform surface, when required, to the leather passing through it, and at the same time to admit of ready adjustment for the passage of any enlarged portions of the materials under treatment. These objects are secured by the mechanism illustrated in the accompanying drawings, forming apart of this specification, in which- Figure l is a side elevation. Fig. 2 is au end elevation, partly in section. Fig. 3 is a detailed view of some of the parts, in section. Fig. 4 is an elevation of standard O, with the shafts S and S in section. Fig. 5 is a detail, view of the piece F and the bar F, in section. Fig. 6 is a plan of the base L, and lever H, with the standard O in section.

L is the bed-plate of the machine, upon which are erected the standards C, in which are located the bearings of the rolls E E', those for the upper roll, E, being placed in slots in which they readily slide up and down, so as to permit of the adjustment of the rolls.

S is the shaft of the lower roll, E, and revolves in fixed bearings in the standard O.

A is a crank to give motion to the rolls.

D D are movable rolls on the outside ofthe standard C. D is kept in its position by the thumb-screw G, and is kept from turning on its shaft by a key.

F is a weight-bar extending between the standards O, each end of the bar being reduced in size so as to ent-er slots in the upper ends of each standard, and to move up and down freely therein. (One of these slots is l represented in dotted lines in Fig. 2.) About the middle of the bar F is a notch in which rests a weight -strap, I, and secured to its under side are two slide-guides, Fl and F having mortises f, through which the shaft S passes. There is also a piece, F, cut to a semicircular shape at the bottom, and adapted to enter a groove in the center of the roll E. The strap I passes over the top of the bar F, and rests in a notch cut in the middle of the bar. The ends i of the Strap pass through the slots Z in the bed of the machine. The end i is attached to the strip I, so as to form a loop, and the end t" is carried farther down, and arranged to suspend a weight, 5.

His a yoke, on which rests the two slideguides F and F. It is pivoted on studs or pivots h, and has strap K, the lower end of which is intended to be fastened to a treadle, by which the yoke may be tilted upward, and thus force the upper roll, E, up and away from the lower roll, E, and in this manner permit the passage of larger obj ects-such as a buckle-between the two than the leather under treatment.

B B are spu1'\\'l1eels, which communicate motion from the lower to the upper roll.

The rolls E E may be made of any desired length, and the grooves of any size or shape to suit the purpose to which the machine may be applied. Y

The short rolls D D may be made of different sizes, and, being readily removed and replaced, a number of different sizes may be furnished with each machine.

The weight 5 may be made of any material and of suitable weight to bring the proper pressure upon any object subjected to the ac I call the machine a rein-rounder, its chief object being to pass reins or other straps through after they have been stitched, as also strips of leather which are not stitched, for the purpose of making them round.

This machine may be constructed of any suitable material. 4

Having described my invention, what I claim, and desire to secure by Letters Patent, is-

tion of the rolls, (when passed between them.)
